It's not just tsunamis that can change the landscape: storms shifted giant boulders four times the size of a house on the coast of Ireland in the winter of 2013-14, leading researchers to rethink the maximum energy storm waves can have - and the damage they can do. Four years ago, storms moved huge boulders along the west coast of Ireland. The same storms shifted smaller ones as high as 26 meters above high water and 222 meters inland. Many of the boulders moved were heavier than 100 tons, and the largest moved was 620 tons - the equivalent of six blue whales or four single-story houses. It was previously assumed that only tsunamis could move boulders of the size seen displaced in Ireland, but the new paper provides direct evidence that storm waves can do this kind of work.<img src="http://feeds.feedburner.com/~r/sciencedaily/earth_climate/tsunamis/~4/Bu59ubVozLg" height="1" width="1" alt=""/>Wed, 28 Feb 2018 09:21:07 ESThttps://www.sciencedaily.com/releases/2018/02/180228092107.htmhttps://www.sciencedaily.com/releases/2018/02/180228092107.htmTiny fossils, huge landslides: Are diatoms the key to Earth's biggest slides?http://feeds.sciencedaily.com/~r/sciencedaily/earth_climate/tsunamis/~3/3nu59NFlewc/180212133446.htm

Velocity decreased in the region of the rupture fault when the earthquake struck, and then gradually recovered, although this recovery showed spatial variability.

The Cascadia Subduction Zone off the coast of the Pacific Northwest has all the ingredients for making powerful earthquakes -- and according to the geological record, the region is due for its next 'big one.' A new study has found that the occurrence of these big, destructive quakes and associated devastating tsunamis may be linked to compact sediments along large portions of the subduction zone.<img src="http://feeds.feedburner.com/~r/sciencedaily/earth_climate/tsunamis/~4/-9QjpfERuh4" height="1" width="1" alt=""/>Mon, 20 Nov 2017 12:45:11 ESThttps://www.sciencedaily.com/releases/2017/11/171120124511.htmhttps://www.sciencedaily.com/releases/2017/11/171120124511.htmLargest, longest multiphysics earthquake simulation created to datehttp://feeds.sciencedaily.com/~r/sciencedaily/earth_climate/tsunamis/~3/Wi0dRNXF9n0/171113111046.htm
